An assistant that plans purchases needs a conflict-of-interest policy

This is a community discussion about the economic risks that arise when AI assistants move from answering questions to taking actions like planning purchases, managing calendars, and creating slides. Meta AI has added these task-planning capabilities in selected markets. The core argument is that because Meta also operates advertising and commerce businesses, an assistant that recommends products creates inherent conflicts of interest that require explicit policy guardrails.

~1,400 years ago, scholars built a rigorous system to verify who you can trust. I rebuilt it as a trust layer for AI agents.

An arXiv paper proposes adapting a classical Islamic scholarly verification framework — originally developed to assess the reliability of information transmitted through long chains of narrators — as a trust mechanism for AI agents. The author argues that when claims propagate through multi-step agent pipelines with varying reliability, a structured chain-of-transmission model could help evaluate source credibility and propagate confidence levels through the system.
